摘要
本文提出了利多多个调谐液体阻尼器（简称TLDS）减小高柔结构多振型地震反应的方法，给出了TLD的布置方案和计算公式，通过钢框架模拟地震振动台试验和理论分析，验证了本文提出的方法的正确性．
The focus of this paper is on the new idea of the Tuned Liquid Damper(TLD) used as the passive control device to reduce the structural responses to earthquake ground motion, in which the approach for controlling the multi-mode responses of tall buildings and high-rise structures with multi-TLD is presented. First of all, the shaking-table experiments of the TLDs-structure system are carried out. And then, the mechanical models and the equations of motion for the systems of tall buildings and high-rise structures with differently installed ways of TLDs are established based on the method of the volume of nuid to solve the dynaAnc liquid pressure and the state equation. The approach in this paper is proved effective through the comparison between the results of experiments and numerical calculations.
